I am looking in to buying a set of unorthodox untra S pulleys but I heard it will cause premature engine damage? I havent noticed any balancers on the stock crank pulley... has anyone ever had any problems?

 

One day I would like to be running those, and I also worry about the same things as you but from reading many threads in the past the answer is still unclear to me.

I have yet to hear a convincing reason either way..


Someone?

 

i'd run the unorthodox, personally the info people post against them just isn't convincing enough, and I think it is a really great mod.

edit: especially great on motors where you are trying to ring out the last little bit of hp. but hell it would be good even on a stock car i suppose.
